On the morning of February 2, Hanoi’s streets were engulfed in dense fog, causing visibility to be limited, many vehicles participating in traffic had to turn on their lights to ensure safety. High humidity in the air (up to 98%), humidity increases the severity of some respiratory diseases and increases the risk of disease outbreaks.

According to the Central Center for Hydrometeorological Forecasting, on February 2, the northern region will be cloudy, with light rain, drizzle and fog in the morning and night. Although the temperature has risen above 20 degrees Celsius, the air humidity is very high (95%).
Humid weather, characterized by low humidity and damp air, creates favorable conditions for disease-causing bacteria, viruses, and molds to grow. Humid weather causes many diseases that affect the health, especially those with weak resistance such as the elderly and children.
Associate Professor, Dr. Nguyen Tien Dung, former Head of Pediatrics Department (Bach Mai Hospital), said that air with too much humidity will create conditions for many viruses that cause respiratory diseases, chickenpox, typhus, and measles. , rubella develops. Among them, young children and the elderly are the most susceptible to infection because children and the elderly have poor resistance so they get sick easily, especially children who are allergic to the weather.
In addition, the current seasonal transition period is also the peak of some respiratory diseases. When infected, if not treated early, the virus can enter the lungs and cause respiratory failure very quickly. At the same time, molds and fungi grow very quickly when it is humid, floating in the air, clinging to clothes, books, blankets, etc., making many people susceptible to allergies and respiratory infections. cause asthma attacks.

Prolonged cold and humid weather also makes many people, especially the elderly, susceptible to respiratory diseases, especially seasonal flu. If you get the flu, the illness is often severe and can easily cause complications like pneumonia and can have unpredictable negative developments.
Along with that, chronic diseases such as bone and joint diseases, stomach and duodenal ulcers, bone and joint pain, blood pressure, cardiovascular disease and bronchial asthma… also often increase and recur when the weather is humid. Unpleasant weather also makes many people feel frustrated, have difficulty sleeping, and eat poorly.
How to deal with stormy weather:
– You should use a dehumidifier to create dryness or turn on the air conditioner in dry mode to reduce humidity. Maintaining air humidity at 40 – 60% is best.
– Clothes need to be dried thoroughly to avoid creating conditions for mold to grow.
– Floors and glass doors are places where water can easily accumulate, causing dampness and slippage, making it dangerous to move, so they need to be wiped regularly with a dry towel. Limit opening doors so that humid air can enter the house.
– To stay healthy during the changing seasons, you need to maintain a scientific lifestyle: sleep on time and get enough sleep; Pay attention to daily exercise to expose yourself to sunlight to increase the body’s resistance against pathogens.
– When leaving the house, you should wear a mask to prevent illness.
The phenomenon of humid weather is the phenomenon of dew forming on the surface of walls, floors, objects, hard surfaces such as wood, stone… that occurs when the air humidity is high (humidity 90% or higher). ). Water vapor in the air is very high, so water often condenses and stagnates on the surface of everything around us. This is a typical phenomenon of the North, usually occurring in late spring (from February to November). 4) causes inconvenience to daily life and greatly affects human health.
